Effect of Ultrasonic Vibration on Precipitation Hardening of Steels and Superalloys

Abstract

Specimens of a 300 grade maraging steel, 17-4 PH steel, A-286, Rene 41, and L-605 were Subjected to ultrasonic vibration during aging. Ultrasonic vibration increased the hardening rate but did not increase the maximum hardness above that of statically aged specimens. The heat treating environment (which included sodium, chloride salts, and air) was found to influence the observed hardening rates of vibrated aged specimens.
